You can remove the extra signs using AC_Toolkit. Make sure there are at least 11 though. I had only 10 at one point and when a neighbor moved out a new one wouldn't move in until i had placed another one in a different location. It seemed that they don't want to move in where one left.

This may not be true but it has worked best for me.
